Upgrading from what version? I don't think I've changed anything for a
long time related to this.

It looks like your qmail-vauth changes $USER environment to "vmail",
which causes dovecot-auth to change the username internally. Since some
people really want this feature, you'll probably have to write a wrapper
checkpassword that unsets $USER before it calls Dovecot's
checkpassword-reply.
